Pi Day!

It is Pi Day today! (It is also Einstein’s birthday, and Talk Like A Physicist Day. See below.) To remind you about Pi Day, from Wikipedia we have:

Pi Minute is also sometimes celebrated on March 14 at 1:59 p.m. If [Pi] is truncated to seven decimal places, it becomes 3.1415926, making March 14 at 1:59:26 p.m., Pi Second (or sometimes March 14, 1592 at 6:53:58 a.m.).

The first Pi Day celebration was held at the San Francisco Exploratorium in 1988, with staff and public marching around one of its circular spaces, and then consuming fruit pies; the museum has since added pizza pies to its Pi Day menu.[1] The founder of Pi Day was Larry Shaw,[2] a now retired physicist at the Exploratorium who still helps out with the celebrations.

Be sure to do some pi-ous things, ok? (Making pies, walking in circles at 1:59 pm (at the 26th second), and so forth… [Update: You can hear more about what to do by listening to this 2004 K C Cole commentary about the day.]

Some other ideas can be obtained from the official site. (And yes, you can study how physicists are supposed to talk – no, no, not really! – for Talk Like a Physicist Day here. Ok, although I somewhat resist going too far with the notion that we physicists are abnormal, my concession might be to have an amusing physics inspired facebook status for some of today. Amusing, I said, so not most of those here. )
